Iprovement in the transpg



vessels for exportation or stored in large reservoirs for futuredisposal, the cars, with the empty tanks, returning for a new load.

Itwill be geen that the above-described mode et' transporting petroleumdemands neither the and excessive laborA required by the present mode ofconducting the transportation of petroleum through the medium ofbarrels, which have to be repeatedly removed from one con-` veyance toanother, are saved.

The following calculation will also tend to demonstrate thadvantages ofmy invention:

The cost eonetauk'of the above dimensions,

will be fty dollars, estimating the number of trips per year attwenty-ive. It would carry in that time five thousand two hundred gallons,and would earn,at a charge of one and one-half cents per gallon,seventy-eight dollars. The present cost of transporting petroleum inordinary barrels, including wastage, insurance, repairs, &c., amounts tofrom ve to seven cents per gallon. Twelve hundred tanks would carry six'million two hundred andv forty thousand gallons perr annum, would cost,at the rate of lifty dollars per tank, sixty thousand dollars,

dollars.

and earn ninety-three thousand six hundred It will be evident that thetanks constructed and owned by the railway companies would be a sourceof profit to the same', while the expense of the costly array of barrelswould be saved to the purchasers ot' and dealers in pe? troleum. *j

I wish it to be understood that I do not desire to claim', eitherwhollyorin part, the method of transporting oil for which Letters Patentof the United States were granted to W. W. Horton onthe 21st day ofMarch, 1865 but I claim as myinven'tion and desire to secure by LettersPatentl The'use for transporting petroleumof truckcars and portablemetal tanks, when the latter are ot' such weight, dimensions, andcapacity that one tank will form an appropriate load for an ordinaryItwo-horse oil-wagon, and when vthe truck-cars are so constructed as tohold and steadily retain a given number of said tanks, all as set forth.l

In testimony whereof Ihave signed my name to this specification in thepresence of two snbscribing witnesses.
